Abstract
Aspects of this disclosure relate to a multiplexer that includes a plurality of filters, a shared filter coupled between each of the plurality of filters and a common node, and a radio frequency filter coupled to the common node. The plurality of filters are configured to filter respective radio frequency signals and have different respective passbands. At least one filter of the plurality of filters includes acoustic resonators and a non-acoustic passive component. Related wireless communication devices and methods are disclosed.
Claims20
A multiplexer with a hybrid acoustic passive filter, the multiplexer comprising:
- a plurality of filters configured to filter respective radio frequency signals, each filter of the plurality of filters having a different passband, and at least a first filter of the plurality of filters including acoustic resonators and a non-acoustic passive component;
- a shared filter coupled between each of the plurality of filters and a common node;
- and
- a radio frequency filter coupled to the common node.
A wireless communication device comprising:
- an antenna;
- and
- a multiplexer in communication with the antenna, the multiplexer including a plurality of filters configured to filter respective radio frequency signals, a shared filter coupled between each of the plurality of filters and a common node, and a radio frequency filter coupled to the common node, the plurality of filters including a first filter that includes acoustic resonators and a non-acoustic passive component.
A multiplexer with hybrid acoustic passive filters, the multiplexer comprising:
- a plurality of filters including a first filter and a second filter having different radio frequency passbands, the first filter including first acoustic resonators and a first LC circuit, and the second filter including second acoustic resonators and a second LC circuit;
- a shared high pass filter coupled between each of the plurality of filters and a common node;
- and
- a low pass filter coupled to the common node.
